Sepax Technologies Inc Sepax HPLC Column Proteomix SCX, NP10, Guard cartridge with holder, 4 x 10 mm
Proteomix ion-exchange phases have been innovatively developed for achieving high ion-exchange capacity, a breakthrough technology for non-porous resins. Proteomix packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead with particle size selections of 1.7, 3, 5 and 10 µm. The PS/DVB resin surface is grafted with a highly hydrophilic, neutral polymer thin layer with the thickness in the range of nanometer. The hydrophobic PS/DVB resin surface is totally covered by a hydrophilic coating that eliminates non-specific bindings with biological analytes, leading to high efficiency and high recovery separations for biological molecules.

Waters Corp BioResolve RP mAb Polyphenyl VanGuard Cartridge w/holder, 450Å, 2.7 µm, 3.9 mm X 5 mm, 3/pk
BioResolve RP mAb Columns contain 2.7-μm superficially-porous-silica particles having an average pore diameter of 450Å. The particles are functionalized with a proprietary polyphenyl bonding process that was specifically designed for LC or LC-MS analyses of intact IgG monoclonal antibodies and their fragments. This Part Number contains (3) VanGuard Cartridges as well as an included VanGuard Universal Cartridge Holder (P/N 186007949).
Waters Corp XBridge Peptide BEH C18 VanGuard Cartridge, 130Å, 2.5 µm, 3.9 mm X 5 mm, 3/pk
The XBridge Peptide BEH C18 130A C18 columns are optimized and QC tested for peptide separations. The small-pore (130Å) trifunctionally bonded BEH particle offers the widest usable pH range, superior low pH stability, and ultra-low column bleed for proteomic, peptide mapping, and synthetic peptide applications. ;This Part Number is for the appropriate VanGaurd Cartridge, designed to protect either the 3.9mm or 4.6mm ID analytical column, and requires the reuable Universal Guard Cartridge Holder (Part Number 186007949)
Optimize Technologies EXP2 Replacement Stems, 0.68µL, 3.0µm EXP, C18, 3pk
Specialized features, patented technology, precision engineering and state-of-the-art manufacturing make the new EXP2 Stem Trap an unbeatable choice for ultra high-pressure trapping applications. Its slim architecture allows it to easily fit into crowded instrument compartments or to connect directly to tightly-spaced injection ports. When tightened by hand, the EXP2 Stem Trap seals to 8,700+ psi. Additionally, the product can be wrench tightened to 20,000+ psi (1,400+ bar). The unique packed floating stem installs directly into any 10-32 port and automatically adjusts to provide a perfect ZDV connection. The new EXP2 design incorporates an integral ferrule into the front-end of the holder so there is no separate ferrule to lose! The replacement stems are also low volume/ low-dispersion, intended for many repeat uses and is available with various bed volume and custom packing options. This product is recommended for nano flow applications. For use with EXP™2 Stem Holder Only
Optimize Technologies EXP Trap Cartridge, 4.6mm x 5mm, 2.7µm HALO, C18, 3pk
The Hand-Tight EXP™ Trap Column is rated to 20,000+ psi. This unique design connects directly to any injection valve (with 10-32 threads) or in-line with 1/16” tubing for unparalleled convenience and efficiency. The EXP™ System enables chemists to quickly remove detergents or salts which can affect the ionization process in MS work. This trapping technique can concentrate the sample directly on-line, allowing for increased recovery of precious sample material compared to off-line techniques. Free-Turn™ architecture allows users to change cartridges by hand without breaking fluid connections on the holder inlet/outlet. The EXP™ Trap Column family now offers packed beds available in 2, 5, 10, 15, 20 and 30mm lengths with diameters ranging from 1-4.6mm and bed volumes from 1.6-600µL. Please contact your representative directly if you're interested in a length other than 5mm.
